EFFECTIVITY:
L. BAT Current Sensor - Serials w/ MCU 14600-001, 14600-002, & 16600-001 (See Figure 24-307)
The BAT current sensor, integral to the MCU, is located on the lower mid portion of the power board
assembly.
(1) Removal - BAT Current Sensor

(b) Remove engine cowling. (Refer to 71-10)
(c) Disconnect battery 1. (Refer to 24-30)
(d) Remove MCU cover. (Refer to 24-30)
(e) MCU 14600-011 & 14600-002: Remove kep-nuts securing 100A fuse to power board
assembly.
(f) MCU 16600-001: Remove kep-nuts securing 125A fuse to power board assembly.
(g) Remove screw, washers, and nut securing bus bar IX
c
to power board assembly.
(h) Remove screws and washers securing BAT current sensor to power board assembly.
(i) Remove BAT current sensor from power board assembly.
(j) Disassemble BAT bus bar stud, nuts, washers, bus bar IX
c
, and bus bar X, from BAT cur-
rent sensor standoff.
(2) Installation - BAT Current Sensor
(a) Acquire necessary tools, equipment, and supplies.
